FAQ

legal questions, answered

Q1.Are these legal calculators a substitute for an attorney?

No. Every result here is an estimate based on published statutory ranges and average fee data. State-specific quirks, fact-pattern nuances, and judicial discretion can move any of these numbers significantly. Use the result to walk into the attorney conversation already framed — not to replace the attorney.

Q2.How accurate is the child support estimator?

It uses the income-shares model used by the five most populous states (CA, TX, FL, NY, PA). Income-shares is the dominant US model, but specific state worksheets diverge on add-ons (childcare, health insurance, extraordinary medical), parenting-time adjustments, and high-income deviations. The estimate is a strong starting point; the actual number from your state worksheet will be within 10-25% in most cases.

Q3.What's the difference between will and trust costs?

A simple will runs $0-500 (DIY/template) to $1,500-3,500 (attorney-drafted). A revocable living trust runs $1,500-3,000 (template) to $4,000-8,000 (attorney-drafted) — but avoids probate, which can cost 3-7% of estate value plus 6-18 months. The will-vs-trust calculator runs the breakeven so you can see when the upfront trust cost pays for itself.

Q4.Can I use these for any state?

The fee-and-cost calculators (filing fees, name change, LLC formation, statute of limitations) are state-aware. Support and dissolution calculators use national medians unless flagged as state-specific. Always cross-check the final number against your state's official court fee schedule before relying on it.
